Ionic AWS Mobile Hub Starter 问题

Question

我按照github readme 上的说明将应用程序导入我的 AWS Mobile Hub 项目并将我的项目 aws-config.js 下载到 src/assets。当我尝试为应用程序提供服务时，出现运行时错误：

Runtime Error:

aws_cognito_region is not defined

Stack:

ReferenceError: aws_cognito_region is not defined

任何见解将不胜感激。

编辑：我在 app.config.ts 代码下方添加了一段我的 aws-config.js 文件（省略了顶部包含我的 AWS 移动中心项目详细信息的常量声明）

app.config.ts：

import { Injectable } from '@angular/core';

declare var AWS: any;
declare const aws_mobile_analytics_app_id;
declare const aws_cognito_region;
declare const aws_cognito_identity_pool_id;
declare const aws_user_pools_id;
declare const aws_user_pools_web_client_id;
declare const aws_user_files_s3_bucket;

@Injectable()
export class AwsConfig {
  public load() {

    // Expects global const values defined by aws-config.js
    const cfg = {
      "aws_mobile_analytics_app_id": aws_mobile_analytics_app_id,
      "aws_cognito_region": aws_cognito_region,
      "aws_cognito_identity_pool_id": aws_cognito_identity_pool_id,
      "aws_user_pools_id": aws_user_pools_id,
      "aws_user_pools_web_client_id": aws_user_pools_web_client_id,
      "aws_user_files_s3_bucket": aws_user_files_s3_bucket
    };

    AWS.config.customUserAgent = AWS.config.customUserAgent + ' Ionic';

    return cfg;
  }
}

aws-config.js：

const 'aws_cognito_region' = 'us-east-1';
... etc

AWS.config.region = aws_project_region;
AWS.config.credentials = new AWS.CognitoIdentityCredentials({
    IdentityPoolId: aws_cognito_identity_pool_id
  }, {
    region: aws_cognito_region
  });
AWS.config.update({customUserAgent: 'MobileHub v0.1'});

Answer 1

我通过转到 aws-config.js 并删除定义的每个变量上的单引号来解决此问题。所以如果你有这个：

const 'aws_cognito_region' = 'us-east-1';

改成这样：

const aws_cognito_region = 'us-east-1';

Answer 2

您需要使用您的 AWS 信息（应用 ID、池 ID 等）配置 src/app/app.config。
